Specification of Letters Patent.

Patented July 13, 1915.

Application filedAugust 18, 1913. Serial No. 785,359.

To all whom it may concern: i v

Be it known that 1, PETER J. LEYEN- DECKER, a citizen of the United States, residing in Haddonfield, Camden county, New Jersey, have invented certain Improvements in Condensers, of which the following is a specification.

My invention consists of improvements in condensers, such for example as those used to condense ammonia gas for refrigerating purposes.

One object of my invention is to so construct a condenser that its contents will be free to fluctuate, thereby permitting agitation of the latter and expeditingcondensation.

Another object is to insure the removal of any uncondensed or foul gases from the condenser.

These and other objects and advantages which will be described hereinafter Iattain in the following manner, reference being had to the accompanying drawings, in which:

Figure 1, isa side elevation of condensing mechanism constructed in accordance with my invention; Fig. 2, is a plan view of Fig. 1, and Fig. 3, is an enlarged sectional view of certain elements which I employ.

Referring to the drawings, Fig. 2 shows two stacks or condensing coils 1 and 2, which are coupled together in a. manner hereinafter described, and as both of the stacks are of similar construction, I will describe only one in detail. Each coil comprises a series of tubes 3 which are connected together at their ends by bends 4. A main gas pipe 5 supplies gas in the present instance through the pipe 6 to the lower of the tubes 3 of the coil, and a series of pipes 7, 8 and 9, connecting with nozzles 10, 11 and 12, respectively, serve to supply gas to said nozzles to be injected into the coils. at different points, as clearly shown in Fig. 1. A pipe 13 communicates with a condensed liquid ammonia take-off header 14 and a nozzle 15 which opens into the pipe 6 adjacent the lower end of the coil, so that a spray of liquid ammonia is injected into the ammonia gas as the latter enters the coil.

The elements so far described form the subject-matter of and are claimed in my U. S. Patents Nos. 1,109,434 and 1,109,435 dated Sept. 1, 1914.

An elbow 16, secured to the upper or discharge end of the coil, has a vertical or upbe liberated pipe 27 secured in the opening 20.

wardly projecting pipe 17 communicating.

therewith. A tank18 is secured to the pipe 17 in the, present'instance by screw threads 19, and has openings 20 and 21 at the top and bottom thereof, respectively. A pipe 22 is supported at its lower end in a threaded sleeve 23 secured within the pipe 17. This pipe 22 has its upper end 24 open and in free communication with the interior of the tank 9 at a point below the top opening 20 in the latter, so that liquid ammonia as it is discharged through the upper end of the coil will pass upwardly through the pipes 17 and 22 andflow over the end 24 of the latter and down into, the bottom of the tank 18, where it will pass through a pipe 25 secured in the opening 21, and thence to the liquid header 14. As the ammonia liquid falls towardthe bottom of the tank 18, as just described, any foul or :uncondensed gases which be contained therein will and pass upwardly through the The pipes 27 are connected by a pipe 28, which is provided with a purge valve 29, and a valve 30 is arranged in each pipe 27 so that said pipes may be closed if desired. The discharge header 14 has take-off piping 31 connected therewith, which is provided with a valve 32 and leads to the liquid ammonia receiving or storage tank, (not illustrated). The pipe 28 communicates with the piping 31 by means of a pipe 33 so as to form a balance or pressure equalizing means between the tank 18 and the liquid discharging piping 31.

Since the nozzles 10, 11 and 12, and nozzle 15, together with their cooperating parts, form the subject-matter of my other applications hereinbefore mentioned, I will omit particular reference to them in the following description of the operation of the mechanism illustrated.

The operation is as follows: .Vat'er is allowed to trickle or run over the tubes of the condenser coils from the top to the bottom from a suitable source such as the perforated pipes 00, and at the same time ammonia gas under pressure passes downwardly from the supply pipe 5 through the pipes 6 into the lower tubes of the coils in the direction of the arrows shown in Fig. l, thence upwardly through the other tubes. As the gas moves upwardly through the coil, it is gradually cooled and condensed by giving of its heat to the coils. The condensed liquid then flows o t of the coils and through the pipes 17 and 22. hen it reaches the upper end of the latter pipe,'it flows thereover and drops into the bottomof the tanks 18, thence through the pipes 25, header l4, and piping 31 to any conveniently located storage tank. While the ammonia liquid is falling into the-tank,-as just de-' scribed, any gas contained therein willbe liberated-and rise to the top of the tank 18, thence out through the pipes 27 into the connecting pipe 28, where it may be removed by opening the purge valve 29. I By having the pipe22 open intoa receptacle or tank with free space therein, as shown in Fig. 3, the contents of the condenser coil Will be free to fluctuate; in other words, the ammonia within the said coils will not be bound. The chief advantages of this construction are; first, that by having the contents of the 'coils'free to fluctuate, the same may be freelyagitated by means such for example as disclosed in my aforesaid applications for patents, thereby tend ing to expedite the condensation of the ammonia gas. Or, if no agitatingmeans is I used, the fact alone that the contentsof the of the tank 18 and allowing sufficiently large soas to act as a storage tank; in this case doing away with the storage tank such as is in common use in refrigerating: apparatus.

The p'pe 28 serves as an equalizing header between the coils, and the pipe 33 connected therewith acts as an equalizing or pressure balance means between the pipe 28 and piping 31. I

I have shown my invention in connection with two coils or stacks, but it will be understood that any number of stacks maybe employed. Also, while I have shown the tanks 18-cooperating with condenser coils of one type, the same may be used with advantage on any type condenser; it only-beeating with said take ofl 7 ing necessary to connect the same to the discharge portion thereof. v

While I have described my invention as being employed in the treatment of ammonia gas the same may be advantageously used to condense other gases such, for example, as carbon dioXid (CO in each case a portion of thecondensed liquid being passed through the nozzle 15 so as to mix with the gas which is to be condensed.

I claim:

1. The combination in condensing apparatus of a condenser body portion having a gas inlet passage and a condensed liquid discharge passage; a fluctuation tank communicating with said discharge passage; a liquid take-0E pipefor said tank; with a conduit communicating with the tank and said takeoff pipe. I

2. The combination in condensing apparatus of a condenser body portion having a gas inlet passage and a condensed liquid discharge passage; a fluctuation tank communicating with said discharge passage; a liquid take off pipe for said tank; with a conduit leading from the top of the tank and communicating with said take-off pipe.

8. The combination in condensing apparatus of a condenser'body portion having a gas inlet passage and a condensed liquid'discharge passage; a fluctuation tank communicating with said discharge-passage;a liquid take-ofi" pipe for said tank; a conduit leading from the top of the tank and communipipe; and a purge valve for said conduit.

4. Thecombination in condensing apparatus of a plurality of condenser body portions, each having a gas inlet passage and V a condensed liquid discharge passage; fluc tuation tanks respectively communicating with said discharge passages; a liquid takemain take-0E P1136 off pipe for each tank; a into whichsaid first take-oif pipes discharge;-Witha conduit communicating with the tanks and'ma'in take-off pipe.

In testimony whereof, Ihave signed my name to this specification, in the presence of two subscribing witnesses.
